I use Xmarks Firefox add-on (formerly Foxmarks) to keep my Firefox bookmarks, saved passwords, etc in sync between multiple computers. Xmarks works like a charm in doing this and I love it.

What is Weave Sync?

Weave Sync is a prototype from Mozilla that encrypts and securely synchronizes your ‘Firefox experience’ across multiple computers. The key difference here is the syncing your Firefox experience and not just bookmarks and passwords.

Weave Sync aims to sync your bookmarks, browsing history, saved passwords and even tabs across various Firefox browsers. So, you have the same exact experience no matter which computer you are logged into – work, home, laptop, desktop or even your mobile device using Firefox Fennec (mobile version of Firefox).

And all this data is safely encrypted before it is loaded into Mozilla’s servers.

First of all thanks a lot for sharing such a wonderful info with us.
basically I haven’t used Weave Sync and the Weave Sync version 0.4 adds some new features those are awesome too. May be in coming future I would like to use it because I just started using “Firefox Bookmark & Password Sync Add-on”. and I like it compare to IE.
thanks
